As already stated, there are lots of different types of stoneware. However, broadly speaking stoneware is a mixture of feldspar, quartz, and ball clay. Feldspars are used as fluxes in clay and glazes. Fluxes reduce the melting point of glass-forming ingredients in clay. Quartz is a mineral with a high content of silica.
